Pg. 460 # 6-18 6. Which of the following describes a situation in which convection would not occur?
A concrete road heated by the Sun does not require convection. Convection can only be in a liquid or gas. What is the temperature scale of the thermometer? Kelvin 8. Is the air around us pure oxygen? Explain. No. It’s also made up of nitrogen, argon, carbon dioxide, methane and ozone 9. Name the layers of the atmosphere indicated by letters in the following diagram. A) Stratosphere B) Thermosphere 10. As a substance cools and its thermal energy decreases what is happening to the motion of the atoms in the substance? The particles are slowing down and colliding with one another much less. 11. Is temperature a measure of thermal energy? Explain. No. Temperature is the measure of average kinetic energy, but thermal energy is the measure of total kinetic energy. 12. Why does atmospheric pressure decrease with increasing height in the atmosphere? Particles move farther apart and collide less so, the air gets less dense and has lower atmospheric pressure. 13. How do high pressure areas and low pressure areas create wind? High pressure air moves into the areas of low pressure. 14. Design and draw a table to compare and contrast high pressure systems with low pressure systems.
High pressure
Low pressure
Cold regions
Warm regions
Brings clear skies
Brings wet weather
Wings move clockwise
Winds move counter clockwise
15. How does the Coriolis Effect differ in the northern and southern hemispheres? It deflects winds counter clockwise in the northern hem. and clockwise in the southern hem. 16. The albino of Earth’s surface changes depending on location. Explain why. Some regions are darker and more closed up than others. Ex. Forests are lower Aledo than cities. 17. Compare and contrast tornadoes and hurricanes. Tornadoes are violent, funnel-shaped columns of rotating air whereas in hurricanes are tropical cyclones. 18. a) East b) a stationary front is shown c) Rain Pg. 481 # 6-15 6. Ice cores, the rings in tree trunks, or fossils. 7. Plant life, soil, geography and climate. 8. El Nino-trade winds moving west weaken and push warm waters eastward La Nina- trade winds are stronger, pushing warm waters farther west 9. a) We would have very cold winters and very hot summers b) Hotter winters and cooler summers 10. Its wobble affects the angle of incidence of the Sun’
12.the dust and debris given off from the impact reflected and absorbed solar radiation causing the atmosphere below to cool.
13. The more elliptical/oval the orbit is, the farther it is from the sun resulting in it getting less solar radiation causing cooler climate. 14. CO2 absorbs solar radiation, keeping Earth warm, but it shows that a long time ago they had less of it meaning that Earth was cooler. Perhaps even going through an Ice Age? 15. a) Winter b) B. it is closer and has straight contact c) B d) B and C. their angle of incidence is almost the same.
